Change detection and repetition detection reflect functionally distinct forms of visual working memory.

ABSTRACT: To examine the roles of change detection and repetition detection in visual working memory, we analyzed three working memory tests expected to rely differentially on these processes. Subjects studied an array of colored squares and then completed three tests. In the complex-probe test, subjects indicated whether a test array matched the study array or if an item's color changed. In the single-probe test, they judged whether a single item's color matched the study color, and in the item recognition test, they identified whether a centrally presented color was studied. We collected same/different confidence responses and analyzed receiver operating characteristics (ROCs) to evaluate memory strength distributions for changed and repeated trials, using a mixture signal detection model to estim
